fire rating

I doubt very much it would be on the prints, what is on the prints is the date of design, you would then have to relate that back to the building codes for that era assuming the building was inspected at the time of construction.

Seems like an unusual request for an existing building.

fire rating

A parapet wall doesn't have a fire rating. It doesn't protect one space from another. He may want the flame spread rating for the materials it is constructed from. The only place to get that is from the materials manufacturer. You'd have to know who that was to get the information. Generally, they will want something with a "class A" flame spread/smoke production rating.

That is not entirely true. Exterior wall parapets usually have no rating requirements, but parapets within the field of a roof very well could as part of a fire wall. If the building inspector is inquiring about an "internal" parapet, then he is inquiring about the possible fire wall. If it is, in fact, a "real" fire wall then, yes, it would be indicated upon the existing plans.
